Question

The chloride that cannot get hydrolysed is :

• A. $SiC{l}_4$
• B. $SnC{l}_4$
• C. $PbC{l}_4$
• D. $CC{l}_4$

Answer 1

The correct option is D $CC{l}_4$

During the hydrolysis, the lone pair electrons on water attacks the metal chlorides, so the central atom should have d-orbital for the reaction to takes place.
$CC{l}_4$ doesn't undergo hydrolysis because of the absence of vacant d-orbitals. But in $SiC{l}_4$ silicon has vacant d-orbitals which can be used for hydrolysis.
Similary $SnC{l}_4,PbC{l}_4$ can undergo hydrolysis due to presence of d-obrital.

Hence, option (d) is correct.
